Application filed June 28, 1916.

To r125 whom it may come m:

h it known that ii, Gnome A. PIPER, a citizen of the United States, and a resident of thin-(ha, in the county of Douglas and, Hate oi iichi-uska, ha c invented a new and improved Lifiingzaiaek and. .ihdiin.;,;- Device, oi which the foilowing is a fuli, clear, and exact description.

This invention relates to lifting 01' puiiing i vices especiaiiy adapted for use in connec- Ti 11 with automobiles as a the axles, and a: a puiier for drawing the automobile out of rats or other places when the car is smiied.

The invention has '0 provide for its general objects device of this charactei: which has the dual function. of lifting and Plliiillg the device being of comparatively simpie and inexpensive construction, i'eiiahle and. efiicicnt in use and so doslgi'ied that it can he i'eadiiy converted for either use.

A more specific object of the invention is the i'ii'ovision oi a lifting iach: oi that type cznnnosed of a phuaiity of each have with an intci'nic hing: pinioin the bars iiciu guided in a casino; so t int the turning of the pinion shaft iii icing hen the jack, the A 2 i t or shoi'ten b are heing' :e um bie from the casing and the pinion being: connected with winding drums, whereby (rabies an be attacied to t ih he :h'uni "\vh the shait is mounted in the the cables when attached to automobile respectively, to )e wouni on the drum in order to puii the iutoinohile out of the piace in which it is stz'ilicd, the drains; having a ratchet and pawl device to pi'ca'eni them from ui'iwinding the caidcs; wi iie the latter are under stress With ohjccts in View, and others which wiii appear as the description pro-- cceds, the invention comprise various novel features; oi (jOiiSii'iH'eiOH and arrau 'einent oi? parts which 'Wiii he set forth with poiidfilb huit in tin. i'oilowiug dc ci'iptiou and ciuini anpendcci hereto.

+-4, Fig, 1; and Fig. is a diagrammatic view showing the device used as a puller.

Referring to the drawing, ii. designates tuhuiav-iihe easing open at both ends and divisihie longitudinally on the linc l into two similar sections which are fastened togethcr by bolts 2 passing through lugs 3 on the sections. Siidahie in the respective scctions are rack bars 4 and 5 which have their teeth 6 presented toward each other, and meshing with the teeth on the opposed have is a pinion 7 on a shaft Eli journaied in the wasing' A. .Bv the turning of the pinion the rack bars move in ()}')P()Sii6 di'i'ections, either lengthening or contracting the jack. ilic rack bars have tubul ar outer extremi- Lies which are lnternaiiy threaded and into the hai" is screwei'i a head stem 9 on which is mounted a head or load-carrying piate 10 connected with the stem 9 by a universai joint 11. in the lower end of the rack bar 5 is screwed a base stem 12 which is fastened to a base plate 13. 33 turning the threaded stems in one direction or the other the jack can he iengthcned or Shortened to suit requii'cnicl'its. Ubviousiy, after the jack has been piaccd in position ,with the base plate 13 resting; on a suitable support and the head 10 engaging the load to he iiited, such as the axle of an automobile, the pinion is turnedby suitable means so that the pinion Wiii ride up on the rack bar 5, and. in turn vause the 'ach hat 4 to move upwardiy. Since the pinion joui'naied in the casing; ii, the casing; inovce upwardiy with respect to the rack bar 3, an Ti ci'inseqi'lcntly the rack bar 4 wiii. move twice the distance of the inoven'ient oi" the casing.

The outer ends of the si'iaft have Winding drums i? and each. composed of inner and outer disks; .H- and 15, respectively. The inner disks have ratchet teeth 16 with which engage pau'is 17 pivoted on the casing at 18 and coi'inccted together by a cross pin 1 These panic; serve to prevent the shaft 8 from turning as the iack is being used to lift a load uh the outer disks or Wheels 153 are spaced teeth or ,iuge 20, so that the foi'hcd end 21 of an operating lever 29 can he engaged with the teeth to turn the pinion-cari ying axle 8 by a i'atchet move inenh the level after having; moved its iinii't being; dieeugac ed. :ironi the te Th 20 of the drums and. moved back so he engaged are fastened to the drums .cables. and in so with different teeth when the lever is again moved forward. The lever is detachable from the jack sothat it will take up little space. and the construction is simplified.

When the device is to be used as a puller the rack bars and attached'parts are removed from the casing by the latter being taken apart. The axle 8 and the (llllllls are left in the casing and the cables and t" B and li respectively, the cable C being attached to the load to be moved, such as the automobile l), *igzfi, and the cable (1, being attached to a stake which is driven in the ground. The drums are now turned so as to wind up the doing the car is drawn toward the stake. In this manner a car when stalled can be moved to a place where the engine of the car, can take care of the load. The cables are normally removed from the drums so as not to be in the way when thedeviee is used as a jack.

From the foregoing description taken in:

connection with the :u'companyi-ng drawclaim as new and desire to ing, the advantages of the construction and method of operation will be readily understood by those skilled in the art to which the invention appertains, and while I have described the principle of operation, to-

gether with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merel illustrative and that such changes may be made when desired as fall within the scope of the appended claim.

Having thus described m v invention I secure by Letters Patent:

A device of the class described comprising a'body, winding drums rotatabl v mounted thereon at opposite sides. teeth on the outer faces of the drums' for engagement with an operating lever, means for turning the, drums, and cables connected with the drums and serving to support the body when one cable is fastened to an anchor and the other cable is fastened to the object to be pulled.
